Who will feed us now?

A son of a lawyer recently graduated from university, also became a lawyer and won his very first trial.
He returns to home excited and shouts, “Hey, dad, today I’ve won my first trial! And, you know, this is the very same trial you have been trying to win all the past 10 years and couldn’t, but I’ve won it in one day!”
Father answers irritably, “Look at this idiot! Today, in single day, he killed the process that fed our family for almost 10 years! Who will feed us now?”
